There is no EU-harmonised rule for melatonin. It sits outside the cannabinoid framework entirely and is governed nationally, with limits ranging from 0.3 mg in Belgium to 2 mg in Spain and no limit at all in several member states. The one EU-level figure is the authorised health claim in Regulation (EU) 432/2012, conditional on 1 mg per quantified portion.
Romania sets no national maximum for melatonin and has not reclassified it as a medicine. Food supplements are placed on the market under Law 56/2021 through notification to the Ministry of Health, and no national list of restricted other substances carrying a melatonin limit was identified.
Romanian practice is openly permissive well above our dose. Melatonin is sold without prescription through the major national pharmacy chains at 5 mg per tablet - five times ours - from Romanian manufacturers as well as imported brands.
